什么是许可软件的最佳和最安全的方法是什么？是否有这样做的现有程序？我想卖我的剧本，但我想，以确保用户无法重新分配或出售自己（当然，如果他们关闭注册自己的计算机，然后选择转售，这是他们的选择）。

该软件语言VB.net。

因为我不知道我是否可以承载任何形式的注册数据库，有没有什么办法让牌自包含的安全？我想用户能够下载的演示，并可以升级到完整版本，不知何故。

感谢您的帮助！

如果没有目前存在做这个软件，我将如何去有关使一个？

因为我不知道我是否   可能拥有的注册数据库   任何类型的，有没有什么办法让   liscensing自包含的安全？

没有，没有办法来安全地做到这一点。即使你有一个注册数据库，它是被攻破。

从演示中取出完整版code。如果您有少量买家，这减轻您的泄漏几率较大。

如果你想复制保护，你应该开始就可以读了。既然你问到这个问题，我可以告诉大家，它会带你很长的时间，以使体面版权保护。这是最好的只是租用别人来为你做。

一个.NET混淆器可能是你最简单，最有效的解决方案。

What is the best and most secure way to license software? Is there an existing program for doing so? I want to sell a script of mine, but I want to make sure that users cannot redistribute or sell it themselves (of course, if they deactivate the registration on their own computer and choose to resell, that is their choice).

The software language is VB.net.

Since I am not sure whether or not I could host a registration database of any sort, is there any way to keep licensing self-contained securely? I would like the user to be able to download the demo and be able to upgrade to the full version somehow.

Thanks for the help!

If there is not currently a software in existence to do this, how would i go about making one?

Since I am not sure whether or not I could host a registration database of any sort, is there any way to keep liscensing self-contained securely?

No, there is no way to do it securely. Even if you do have a registration database, it is crackable.

Remove full version code from the demo. If you have a small amount of buyers, this lessens your chance of leakage greatly.

If you want to make copy protection, you should start reading up on it. Since you are asking about this, I can tell that it will take you a very long time to make decent copy-protection. It's best to just hire someone else to do it for you.

A .net obfuscator is probably the easiest and most effective solution for you.
